September 28, 2017-The US Food and Drug Administration (FDA) has issued a letter to health care providers advising that the agency is evaluating recent information regarding type IIIa and IIIb endoleaks with the use of endovascular graft systems indicated for endovascular aneurysm repair (EVAR) procedures. The letter, addressed to vascular and cardiothoracic surgeons, radiologists, and cardiologists, stated that an increase in the occurrence of type III endoleaks has been suggested by several sources, including the FDAs Medical Device Reporting system and the Annual Clinical Updates to Physicians by the manufacturers. This increase is compared with earlier clinical update reports in patients with various device models and implant duration lengths, including some patients who had previously stable repairs.. The purpose of the FDAs letter is to bring this potential complication to the attention of health care providers and to remind and encourage them to report type IIIa and IIIb endoleak events ...
Fenestrated and branched endovascular aortic repair (F/B-EVAR) is associated with a high degree of technical and clinical success. Despite this, studies have also reported high reintervention rates, and these are often related to the bridging stent grafts. Often new devices appear on the market before they have been tested in the bridging stent graft position. This review aims to assess the current literature on bridging stent grafts and discuss complications, illustrated by case reports. Complications reported with bridging stent grafts include; endoleak, kink, fracture, migration, occlusion, stenosis and perforation. Some known risk factors for bridging stent occlusions are renal artery stent grafts vs. SMA and celiac artery stent grafts. Some device specific complications have also been reported such as type IIIc endoleak with the Lifestream stent graft (Bard Peripheral Vascular, Tempe, AZ, USA) fractures and type IIId endoleaks with the 1st generation of Begraft (BentleyInnoMed, Hechingen, ...
Instead of open aneurysm repair, your vascular surgeon may consider a newer procedure called an endovascular stent graft. Endovascular means that the treatment is performed inside your artery using long, thin tubes called catheters that are threaded through your blood vessels. This procedure is less invasive, meaning that your surgeon will usually need to make only small incisions in your groin area through which to thread the catheters. During the procedure, your surgeon will use live x-ray pictures viewed on a video screen to guide a fabric and metal tube, called an endovascular stent graft (or endograft), to the site of the aneurysm. Like the graft in open surgery, the endovascular stent graft also strengthens the aorta. Your recovery time for endovascular stent grafting is usually shorter than for the open surgery, and your hospital stay may be reduced to 2 to 3 days. However, this procedure requires more frequent follow-up visits with imaging procedures, usually CT scans, after endograft ...
OBJECTIVE This study reports the early and midterm to long-term experience of chimney grafts (CGs) in urgent endovascular repair of complex lesions in the thoracic aorta. METHODS Twenty-nine high-risk patients (20 men) who were unfit for open repair were treated using CG technique for ruptured (n = 14) or symptomatic (n = 15) aortic lesions engaging the aortic arch itself (n = 9), the descending aorta (n = 10), or the thoracoabdominal aorta (n = 10). Twenty-two patients (76%) were treated urgently (≤24 hours) and seven were semiurgent (≤3 days). Of 41 chimneys used, 24 were placed in supra-aortic branches and 17 in visceral branches. Median follow-up (interquartile range) for the entire cohort was 2 years (0.6-3.8 years), 2.5 years (1-4 years) for 30-day survivors, and 3.5 years (1.9-6.4 years) for those who were still alive. RESULTS Four patients (14%) died ≤30 days of cerebral infarction (n = 1), visceral ischemia secondary to the initial rupture (n = 1), multiple organ failure (n = 1), or
Dr. Courtney M. Townsend, Jr. (right), President of the American College of Surgeons, presents Dr. Timothy A.M. Chuter (left) with the 2017 Jacobson Innovation Award. Between 1993 and 2000, there was rapid expansion in the scope of endovascular aneurysm repair including the first endovascular repair of a ruptured aortic aneurysm (1994), the first endovascular repair of an aortobronchial fistula (1995), the first bifurcated stent grafts (1993), the first inflammatory aneurysms (1995), the first fenestrated stent grafts for aneurysms of the pararenal aorta (1998), and the first branched stent grafts for the thoracoabdominal aorta (2000). Although none was the work of a single inventor, Dr. Chuters trailblazing work was pivotal in this rarefied period of surgical breakthroughs, not simply by his invention of new forms of endovascular aneurysm repair, but also through his mentoring of surgical residents, fellows, and faculty. Notably, Dr. Chuter has nurtured his inventions from conceptualization to ...

different portions of the stent/stent graft 10 are heat set at different diameters. For example, a braided material could be fabricated on a mandrel having a first larger diameter (e.g., 30-35 mm), which is generally the maximum diameter to which the stent/stent graft would be capable of expanding. The braided material may then be pulled down or compressed onto a mandrel having a second smaller diameter (e.g., 20-25 mm) and heat set such that the heat set stent/stent graft is capable of self-expanding to the diameter of the second smaller diameter. However, when the stent/stent graft 10 is axially compressed, the stent/stent graft is capable of expanding to the first larger diameter. Thus, in order to deploy the stent/stent graft 10, the distal end 34 of the stent/stent graft 10 may be positioned distally of the aneurysm 14 and as the delivery catheter 38 is retracted, the distal end of the stent/stent graft engages the lumen 12. As the stent/stent graft is further deployed in the region of an ...
In this issue of the Journal, Howell et al. (1)present some tuly remarkable results. Working in an interventional cardiology suite, they were able to implant the Medtronic AneuRx stent graft in all but one of 215 patients. Most of these patients had major comorbidity with an American Society of Anesthesiologists grade of IV or higher in 58.6% of patients. All these sick patients underwent stent-graft implantation under general anesthesia, yet only one patient suffered a non-Q-wave myocardial infarction, none died in the perioperative period, and most went home the next day.. One notable aspect of the technique described by Howell et al. (1)is the use of the Prostar XL device to facilitate percutaneous arterial closure. The 16F contralateral access site was closed this way in 174 of 188 attempts, and the 22F ipsilateral access site was closed in 26 of 27 attempts. Few centers have achieved such a high rate of success with percutaneous arterial insertion of large-bore sheaths. Indeed, one wonders, ...

We studied the use of carbon dioxide (CO 2) as a non-nephrotoxic contrast agent for EVAR. Methods: Recorded data from 114 consecutive patients who underwent EVAR with CO 2 as the contrast agent over 44 months were retrospectively analyzed. CO 2 was used exclusively in 72 patients and in an additional 42 patients iodinated contrast (IC) was given (mean, 37 mL). Renal and hypogastric artery localization and completion angiography were done with CO 2 in all patients, including additional arterial embolization in 16 cases. ...
Abdominal aortic aneurysm repair has undergone a revolution since Volodos and Parodi described endoluminal repair in the early 1990s. Subsequent data from large registries have confirmed its efficacy. Randomised controlled trials have shown that although endoluminal repair may not be as cost effective as open repair, it can be performed with a lower mortality in patients fit for open repair. Some European countries (eg, Belgium) have taken the results of these trials to rationalise the number of hospitals able to do endovascular repair. The devices continue to improve and although most require open surgical access at present, in future percutaneous access will become the norm. This article reviews the current state of endoluminal aortic aneurysm repair in the infrarenal aorta. ...

First generation aortic endovascular stent-grafts (EVG) had low applicability and were associated with a significant incidence of peri-procedural complications. With time, a number of EVG systems perished (some predictably) in a "survival of the fittest". Improvements in design have been made as a result of these failures. Current designs have low peri-procedural morbidity and mortality and improving durability. This paper sets out to discuss the use of a variety of EVG for abdominal aortic aneurysm repair. The ideal properties of an EVG will be outlined along with some of the advantages and limitations of current, and, where appropriate, historical, commercially available stent-graft systems.. ...

RnRMarketResearch.com adds "MediPoint: Aortic Stent Grafts - APAC Analysis and Market Forecasts" to its store.. Aortic stent grafts are most commonly used to reinforce a weak spot in an artery, which is known as an aneurysm. The stent grafts are designed to seal tightly with the patients native artery above and below the aneurysm, and are used to treat abdominal aortic aneurysms as well as thoracic aortic aneurysms. Aortic aneurysms, as opposed to aneurysms found elsewhere in the body, are potentially very serious, as a burst aorta results in massive internal bleeding that can be fatal unless treated rapidly by an experienced emergency medical team. Since their introduction in patients in 1991, aortic stent graft devices have gained wide acceptance and availability, with their adoption fueled in great part by advances in stent-graft design and by a variety of devices for various anatomic features. Over time, these devices have gained traction for use in patients with ruptured aneurysms because ...
Boomington, Ind. ─ Cook Medical has received premarket approval from the U.S. Food and Drug Administration (FDA) for its lower-profile Zenith Alpha™ Thoracic Endovascular Graft. Zenith Alpha Thoracic is indicated for the endovascular treatment of patients with isolated lesions of the descending thoracic aorta (not including dissections) having vascular anatomy suitable for endovascular repair1. The approval of Zenith Alpha Thoracic was based on two pivotal clinical trials that studied the safety and effectiveness of the device in patients with aortic aneurysm/ulcer or blunt traumatic aortic injury.. Zenith Alpha Thoracic will allow physicians to treat more patients with TEVAR (thoracic endovascular aortic repair) because of its lower-profile introduction system and broad range of sizes. With a 16-20 French delivery system, Zenith Alpha Thoracic was developed to address vascular access issues associated with larger-profile devices and to increase conformability in tortuous anatomy..

Aortic aneurysm repair requires only a small incision in your artery. The surgeon will usually access your femoral artery, which is a branch of the aorta, by making a small incision in another part of your body, such as your groin. He or she will first insert a wire through the incision and into your femoral artery. The wire will help guide a long thin tube, called a catheter, through the inside of the arteries to the place of the aneurysm. The catheter can safely navigate through the inside of arteries; it reduces the risk of the procedure, allows for a quicker recovery , and reduces pain. Your arteries have no nerve endings so you should not feel any pain as the wire moves through them. The surgeon guides the catheter to the aneurysm and puts the stent graft into place to repair the weakness. Some stents slowly release medications to help prevent blood clots and other problems after the procedure. After the stent is securely in place, the surgeon removes the catheter, closes the incision ...

SCVS 2018 Abstracts: Statin Therapy is Associated with Higher Long-term, but not Perioperative Survival after Abdominal Aortic Aneurysm Repair
概述:The neck of a juxtarenal aneurysm is often too short for stable hemostatic stent-graft implantation. Fenestrations (holes) in the stent-graft permit implantation at a more favorable level by providing a route for flow to the renal arteries. In cases of pararenal and thoracoabdominal aortic aneurysm, the aorta around the renal and visceral arteries is too dilated for hemostatic contact with the wall of the stent-graft. There is a gap, which must be bridged by a branch of the stent-graft. In ...

BACKGROUND: The chimney technique has been successfully used to treat juxtarenal aortic aneurysms. The two main issues with this technique are gutter formation and chimney graft (CG) compression, which induce a risk for type Ia endoleaks and stent thrombosis, respectively. In this benchtop study, the geometry and renal artery flow of chimney endovascular aneurysm repair configurations were compared with chimney configurations with endovascular aneurysm sealing (ch-EVAS). METHODS: Seven flow phantoms were constructed, including one control and six chimney endovascular aneurysm repairs (Endurant [Medtronic Inc, Minneapolis, Minn] and AFX [Endologix Inc, Irvine, Calif]) or ch-EVAS (Nellix, Endologix) configurations, combined with either balloon-expandable or self-expanding CGs with an intended higher positioning of the right CG in comparison to the left CG ...

BACKGROUND: Fenestrated endografts are customized, patient-specific, endovascular devices with potential to significantly reduce morbidity and mortality of short-neck infrarenal and juxtarenal abdominal aortic aneurysm repair. The Zenith fenestrated endovascular graft (ZFEN) for abdominal aortic aneurysms (Cook Medical, Bloomington, Ind), Food and Drug Administration-approved in 2012, remains the only fenestrated device available in the United States. This technology is among the most technically complex catheter-based procedures and, therefore, inherently associated with serious risk for device-related complications. We sought to define patterns of physician and hospital adoption of ZFEN. METHODS: Deidentified datasets containing numbers of physicians trained, orders by physicians and hospitals, and designs (fenestration/scallop configuration) was provided for U.S. ZFEN devices ordered (April 2012-August 2015). We evaluated the number of physicians trained, the number of devices ordered, hospital

During an endovascular repair procedure, the patient is placed lying on their back on an X-ray table. A tiny cut will be made over the insertion site in your groin and a small tube called a catheter will be inserted into the artery. With the help of X-ray imaging, the physician slowly advances the catheter to the site of the aneurysm. The catheter contains a stent graft made of fabric with metal stents. The stent graft helps to decrease pressure on the aneurysm site by directing blood through the graft.. After the procedure X-rays are taken to make sure the stent graft is in place and no blood is leaking. The graft is expanded and held in place against the artery wall using small hooks or pins. The catheter will be removed and the incision in your groin will be closed.. ...
RESULTS:: From 104 patients selected, 4 (3.8%) preferred primary hospitalization and were excluded from further analysis. Four patients (4%) with access vessel complications required additional procedures and had to be hospitalized overnight. The 30-day readmission rate was 4% (4), all due to access vessel stenosis (2) or false aneurysm (2). There was no 30-day mortality. From the 96 outpatients who completed Outpt EVAR, 93 (97%) would undergo Outpt EVAR again and would recommend it to others. Cost comparison showed in 42 matched contemporary patients treated with just a standard stent graft that costs were significantly lower in 21 Outpt EVAR patients than in 21 inpatient EVAR ...
An endoluminal graft includes a unitary tube of graft material forming two adjacent legs that are integral and monolithic to each other. The graft can be part of a prosthesis assembly for treatment of branched vascular systems and can function as an integral bifurcated leg extension prosthesis in combination with a main bifurcated prosthesis. In treating abdominal aortic aneurysms, the graft can be deployed within both iliac arteries.

The use of endovascular aneurysm repair (EVAR) in the treatment of abdominal aortic aneurysms has advanced from a premature characterization as a "failed experiment" in early 2000 to the predominant modern method of treatment. Technology has accommodated initial shortcomings, but it has also led to expansions in the treatment of ruptured aneurysms and complex aortic pathologies. The overall aim of this thesis is to characterize the contemporary utilization of endovascular repair in the international setting and to evaluate its expanding use in complex aortic disease treatment.. Paper I is an analysis of outcomes after intact aneurysm treatment from registries of 12 countries. From 2005 to 2013, and with 83,253 patients included, it was shown that the use of EVAR has increased while, the perioperative mortality has decreased. This was counterbalanced by a worsening mortality for those patients treated with open aortic repair.. Paper II is an analysis of ruptured aneurysms from the above-mentioned ...
In an attempt to chart the changing rates of open, EVAR and branched/fenestrated EVAR repairs over the past decade, Suckow and colleagues used a query of Medicare claims data from 2003-2013 involving abdominal aortic aneurysm repairs (excluding open repairs with any thoracic component but including juxta-/pararenal procedures).. The data gathered showed a 20% decline in all forms of abdominal aortic aneurysm repair to approximately 24,000 repairs in 2013 following a peak of approximately 30,000 in 2005. Breaking these figures down by procedure type, the number of EVAR procedures grew by 74% from 2003-2008 before falling by 13% to 2013. Open repair saw a prolonged and significant decline from 2003 to 2013, falling by 78%. Less than 4,000 open repair Medicare procedures were completed in 2013, Suckow said. Branched/fenestrated EVAR-first coded by Medicare in 2011-has since increased by 504% and by 2013 was as common as open repair.. As well as looking at the total number of repairs, the team also ...
An apparatus for endovascular repair of aortic aneurysms is disclosed. In one form, the apparatus includes a tube and an anchoring unit that includes a plurality of thin lines. The tube serves as a conduit for blood flow in an aneurysm of an aorta. First end of the lines are connected to a first end of the tube. Second end of the lines are separated by a distance from the first end of the tube for anchoring the apparatus at a location away from the aneurysm.
A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.

The utilization of endovascular abdominal aortic aneurysm repair (EVAR) in suitable patients has resulted in decreased perioperative morbidity and mortality. Octogenarians as a subgroup have been more readily offered EVAR, as it is less invasive, and
Several large-scale trials comparing EVAR to open surgery for AAA have been published. Short-term surveillance consistently shows better outcomes for EVAR in respect to mortality. Also, EVAR is milder on patients and better tolerated. However, a well known advantage for open repair of AAA is that it is durable. Less surveillance is needed for these patients in comparison to patients undergoing EVAR. This makes open repair a preferred option for younger, healthier patients who can withstand the procedure and are believed to have a long life expectancy.. The EVAR 1 trial was a prospective, randomized trial comparing EVAR to open repair of AAA in over 1200 patients. In 2010 long-term follow-up was reported (median of 6 years). As expected, peri-procedural mortality was greater with the open repair (6%) than in the endovascular repair (2.3%). These short-term benefits remained at 6 months, but disappeared within 4-6 years, a time at which aneurysm and total mortality curves converged for both ...
A randomized trial found that patients had similar rates of survival and quality of life whether they underwent elective open and endovascular repair of their aortic abdominal aneurysm (AAA). The procedures also had similar costs and cost-effectiveness ratios.
A radially expandable endoluminal stent-graft assembly (10) and a method and apparatus for making the same are described. The stent-graft assembly (10) includes a tubular radially expandable stent (12) circumferentially covered by a tubular graft (14) which is retained about the stent (12) by inherent radial recoil forces of the tubular graft (12) and without the need for adhesives or sutures to retain the graft (14) on the stent (12). The assembly apparatus (44) for making the expandable stent-graft assembly (10) consists generally of a tapered dilation mandrel (46), a stent retaining mandrel (52), a handle (53), and couplings (60, 71) for removably and coaxially coupling the components of the assembly apparatus mandrel (44). The method for making the expandable stent-graft assembly (10) utilizes the assembly apparatus (44) to make the stent-graft assembly (10) by dilating the graft (14) on the tapered dilation mandrel (46), sliding the dilated graft (14) over a stent (12) retained on the stent
In the meeting international experts, with the most significant experience in endografting, often gained from constant involvement in this activity for almost a decade, discuss the critical issues in endografting. The best available, most up-to-date information and data are used in presentations, and discussions that follow are in depth. Most importantly, consensus reached has a large bearing on what happens in endografting throughout the world over the year that follows the meeting. What direction will endografting take following this most recent meeting? A decade on in endografting from its introduction, data from early generation devices show the pattern of success or failure, depending on how one wishes to look at it. Nearly all of the experts at the meeting are convinced that endovascular exclusion of aneurysms is a viable alternative to aortic surgery and only a few believe they should continue with caution. Is it that they have got used to the occasional catastrophic device failure? Is it ...

An endoluminal stent is formed in a modular construction to include at least one elongate spine and a plurality of general tube-defining modules attached to the spine, or spines, in a longitudinal array. The modules are constructed along a spine-like structure so as to form a bifurcate shape for implantation in branching or bifurcating vessels. Each module defines, in cooperation with a spine, a closed ring-like structure. Each of the modules is radially expandable from a reduced diameter, low profile configuration, in which it is readily navigated through the body passages, to an expanded diameter engageable with the inner luminal surface of the body lumen. The stent, being of modular construction, can be built to individual specifications for a specific patient. Modules are formed from a wire shaped in a flat serpentine configuration that is then wrapped in a cylindrical configuration with its free ends connected to a spine. The modules are expandable, as by a balloon, from a low profile to an

Introduction: Endovascular aneurysm repair (EVAR) has been an established treatment for abdominal aortic aneurysm (AAA). Although statin use has been shown associated with better long-term survival following open AAA surgery, its impact on EVAR has not been systematically explored.. Methods: We retrospectively analyzed a multicenter database of 368 consecutive patients (age, 76 ± 8 years; 84% male) undergoing EVAR for AAA between November 2006 and December 2013. The outcome measure was overall survival following EVAR. Independent predictor associated with the outcome was assessed by Cox proportional hazard regression model. Furthermore, the association between the statin use and the outcome was assessed.. Results: During the follow-up of 30 ± 20 months, 38 patients died from cardiovascular disease (33%), cancer (23%) or infection (23%). Survival rate was 96% and 81% at 1 and 5 years, respectively. In Cox regression analysis, statin use (in 213 AAA patients, 58%) was negatively associated with ...
PURPOSE: To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE: Open arterial access is obtained to both common femoral arteries and the left subclavian artery (LSA). Access to the visceral and renal arteries is obtained through separate 8-F sheaths for each visceral and renal branch. Both visceral arteries (celiac trunk and superior mesenteric artery) are accessed through 2 separate sheaths placed into the LSA, and both renal arteries are accessed through 2 separate sheaths placed into the left common femoral artery. Corresponding covered stents are introduced and positioned in the celiac trunk, superior mesenteric artery, and both renal arteries but not deployed. The aortic stent-graft is then introduced and deployed through the right common femoral artery. Once the aneurysm exclusion is completed, ...
OBJECTIVE: The purpose of this study was to assess whether there is a difference in outcome of endovascular repair in patients with and without intraoperative adjuvant procedures. METHODS: Demographic, anatomic and operative details were assessed in patients undergoing endovascular repair using the EUROSTAR registry and correlated with morbidity and mortality rates. Three groups of adjuvant procedures: (A) endovascular, (B) surgical peripheral arterial and (C) surgical abdominal arterial were compared with a group of patients without an adjuvant procedure (D). Logistic regression and Cox proportional hazards model were used for statistical analysis. RESULTS: Of 4631 endovascular repairs, 1353 patients (29.2%) required adjuvant procedures. Additional endovascular procedures were performed in 1057 (78.1%), surgical peripheral arterial in 193 (14.3%) and surgical abdominal arterial in 103 (7.6%). The 30-day mortality rate was significantly higher in categories with peripheral arterial surgical ...
